Unusual Hydatid Cysts: Cardiac and Pelvic-Ilio femoral Hydatid Cyst Case Reports and Literature Review.

Abstract

IntroductionHydatid cyst is a parasitic disease caused by Echinococcus granulosus, most commonly seen in the liver and lungs. The hydatid cyst is rarely seen in the heart and iliofemoral region, representing less than 2% of all cases. In this article, we report our cases of hydatid cysts in unusual loci.MethodsBetween 2015 and 2018, 6 rare cases of hydatid cysts were diagnosed at the Cardiovascular Surgery Department of Harran University. Four of these patients had cardiac localization and two patients had their cysts located in the iliofemoral region, extending to the pelvic zone. All patients were female. Three patients had no other organ involvement. One patient with cardiac hydatid cyst underwent normothermic cardiopulmonary bypass + total pericystectomy + Cooley-like aneurysmectomy. Total pericystectomy was performed in three other patients with intrathoracic locus by normothermic cardiopulmonary bypass. Two patients who were referred to our clinic with palpable iliofemoral mass were evaluated with appropriate imaging methods and diagnosed accordingly. Multiple iliofemoral cysts were managed with pericystectomy and drainage by a single incision made over the inguinal ligament.ConclusionHydatid cyst disease can develop in cardiac chambers and inguinal region with or without hepatic or pneumatic involvement. Normothermic cardiopulmonary bypass can be safely used in patients with cardiac hydatid cysts, and capitonnage similar to ventricular aneurysm repair in patients with a widely involved cystic lesion can be very useful for the protection of ventricular functions.
